How can i synchroize the wallet?
Go to Menu at the top left. Click on Network Monitor and you should see Peers and Blocks. Afterwards, click on the Blocks. Check what is the time of the last block. It should be above 668843.
Let me get this right: Are you sending from the Android wallet or to the Android wallet? If it's from the Android wallet, check the address on Binance and if it matches the one stated in the transaction.
